A=1/2bh
Divide by h and 1/2
2Ah=b
Answer: The answer to the first question is C(20%)
Step-by-step explanation: 1. you need to find the absolute decrease which is subtracting 350-280= 70.
2. now you need to find the percent decrease which is dividing the absolute decrease by the whole price.. so.. 70/350= .20
3. now just multiply .20 *100 = 20%
You want to figure out the relationship between -3 and -8. the simplest one is subtraction: -3 - 5 = -8
your x value, -3, minus 5 equals -8, your y value
so the rule for this is x - 5 = y
Answer:
Step-by-step explanation:
Keep in mind that the tangent function is negative in Quadrants II and IV.
Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.
If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.
